power: supply: da9150-fg: Remove unnecessary print function dev_err()

The print function dev_err() is redundant because
platform_get_irq_byname() already prints an error.

Eliminate the follow coccicheck warning:
./drivers/power/supply/da9150-fg.c:524:2-9: line 524 is redundant
because platform_get_irq() already prints an error
